Product introduction
Model name: 8290-191
Suitable for all kinds of electrical systems, electroplating, electrolysis industry AC high current measurement and control, the product has the following characteristics:
● Product input saturation: Because the product adopts the rogowski principle, abandoning the traditional transformer principle or the Hall principle must be used in the magnetic core, so that the product input range can be very large without affecting the performance of the product;
● Fast response time: the response time of this product can reach us level, which can be applied to the fault recording of the power system;
● Product frequency response width: the product’s bandwidth range can reach more than 20khz, can be widely used in the input waveform complex signal detection;
● Good product linearity: the linearity of product output can reach 0.2%, which can reflect the size of the input signal;
● High product accuracy: the overall accuracy of the product is within 1%;
● Small volume, light weight: compared with the traditional transformer principle and Hall principle products, under the same input range, the product is smaller in volume and lighter in weight;
